--- title: Galaxie® GH url: "https://www.wittenstein-group.com/en-us/product/galaxie-gh" date: 2026-02-12 modified: 2026-02-24 lastUpdated: 2026-04-13 --- # Galaxie® GH Galaxie® GH gearbox The Galaxie® GH gearbox offers maximum flexibility for integration into complex machine concepts. Thanks to the integrated angled step, the mounting position can be variably adjusted – ideal for confined installation spaces or special design requirements. At the same time, the GH impresses with its proven Galaxie® kinematics with flat tooth engagement, high torque density and an optional large hollow shaft for applications with media or shafts. This makes the Galaxie® GH the ideal solution for sophisticated automation and robotic systems with high demands on precision and freedom of installation. ![](https://www.wittenstein-group.com/typo3temp/assets/_processed_/b/c/csm_RGK-IMAGE_320d292a53.webp) ### 72 – 240 Ratio ### 1086 – 4050 Nm Max. torque ### 0 arcmin Backlash [ Technical details ](#tech-details) [ Customized solutions ](#solutions) [ Related products ](#related) [ Request consultation ](#consultation) ![](https://www.wittenstein-group.com/epim-fs/Wittenstein-Prod-static_content/usp/12-precision.svg) ###### Highest precision ![](https://www.wittenstein-group.com/epim-fs/Wittenstein-Prod-static_content/usp/55-stiffness.svg) ###### Maximum rigidity ![](https://www.wittenstein-group.com/epim-fs/Wittenstein-Prod-static_content/usp/4-12-compact.svg) ###### Optimized installation space - Technical data - Available options | | | **Galaxie® robustness line** | |---|---|---| | | | 110 | 135 | 175 | | Variant | | GH | GH | GH | | Outer diameter1 | D \[mm\] | 160 | 191 | 241 | | Length2 | I \[mm\] | 215 | 260 | 302 | | Max. acceleration torque3 | T2B \[Nm\] | 1086 | 1800 | 4050 | | Max. output speed3 | n2max \[rpm\] | 95 | 80 | 61 | | Nominal output torque3 @ n2N | T2N \[Nm\] | 450 | 750 | 1685 | | Nominal output speed3 @ T2N | n2N \[rpm\] | 23 | 20 | 15 | | Emergency stop torque3 | T2Not \[Nm\] | 3000 | 5400 | 12000 | | Torsional rigidity3 | Ct21 \[Nm/arcmin\] | 370 | 650 | 1400 | | Ratio4 | i | 72 - 240 | | 1 Without connectors / varies depending on mounting position 2 Without cooling connectors / varies depending on pre-stage and motor-dependent adapter plate 3 values are subject to variations due to factors beyond our control 4 output rotates in opposite direction to input Technical data not binding; specified values only valid with hollow shaft version/MF3 (with additional coaxial preliminary stage) on request | | **Note** Optional hollow shaft with hypoid pre-stage.
